AN Australian company has produced the men's equivalent of the "Wonderbra" - a range of "Wondercup" underwear designed to enhance the apparent size of the contents.

"It basically lifts, separates and extends," aussieBum founder Sean Ashby was quoted as saying by the national AAP news agency.

"This design uses all of the natural assets of the person, whether they be big, small or indifferent."
The underwear features a "wondercup," a pouch used to "separate and stop squashing."

Ashby said the design, launched last week, had attracted a lot of interest in the United States and Europe.

The marketing campaign features the slogan: "The new 'wondercup' technology in these attention-grabbing, all-cotton Patriot briefs will have you seriously looking bigger and feeling amazing."

The brand is sold in some of the biggest department stores in the world and is distributed to more than 70 countries via Internet sales.
